OIL-TAN K.

Application filed July 27, 1915.

T 0 all whom it may concern:

Be it known that I, J osnrn A. BUTCHER, a citizen of the United States, residing at Sulphur, in the parish of Calcasieu and State of Louisiana, have invented certain new and useful Improvements in Oil-Tanks, of which the following is a specification.

This invention relates to improvements in oil tanks generally, more especially for guarding the same against explosions from lightning.

The invention has for its object to carry out the aforesaid end in a simple, inexpensive and effective manner.

The invention consists therefore of certain instrumentalities and features of construction substantially as hereinafter fully disclosed and defined by the appended claims.

In the accompanying drawings is illus trated the preferred embodiment of my invention wherein it will be understood that various changes and modifications may be made as to the detailed construction and arrangement of parts without departing from the scope of the claims, and in which draw- 1ngs- Figure 1 is a sectional elevation thereof, the roof or closure being in place.

Fig. 2 is a horizontal sectlon, taken just above the outlet or delivery pipe connection.

In carrying out my invention, I provide the tank or holder 1 with a shallow waterholding receptacle 2, suitably secured by bolts or otherwise within the upper end, of the tank; a frame or additional support 3 therefor being also secured thereunder and to said tank, said frame being constituted preferably of centrally crossing bars. Upon the tank or holder 1 is suitably superposed a conical roof or protector 4, with its rafters 5 secured to horizontal beams 6 suit-ably secured upon the top-edge of the tank or holder, said roof or protector having its sheathing of asbestos or other non-inflammable material 7 and, yet in event of any portions of the roof becoming mutilated or otherwise rendered non-protectivefrom fire or lightning the falling, or fragmental, portions thereof would be received within the water-receptacle 2 and thus be prevented from contact with the oil in the tank, accordingly guarding against firing the oil.

A suitable inlet-pipe or intake 8 connects with the tank or holder 1, about centrally of Specification of Letters Patent.

its bottom, for supplying the oil to the tank the oil being delivered or taken therefrom by means of an outlet-pipe or outtake 9. The pipe or outtake 9 communicates with the tank, just below the water-receptacle 2 and is adapted at that point to receive and carry off accumulating gas upon the oil-surface, as well as to perform its primary function of delivering the oil from the tank. The pipe 9 18 carried downwardly under or below the surface of the ground about two feet and has a horizontal extension or portion 10 and this latter has an upward extension 11 with a suitable T-terminal 13 for the suitable attachment thereto of branch-pipe (not shown) as may be called for in distributing the oil for use. The pipe-extensions 10, 11 are suitably incased or protected in tiling (not shown), as well understood. The pi eextension 10 is equipped with a suita le plug-valve. 12 for cutting off the ignited or burning oil in event of the same taking fire, from the source as above indicated, at the discharge end as at 13 of the delivery pipe, the same being the more exposed, above grouml, and, of course, likely to receive a lightning stroke. At the opposite side of the oil tank or holder 1 is a screw-plug 14 adapted to be removed in event of the appearance of flame at that side of the tank, or for the venting of the tank for the escape of gas-accunmlatious, in the event of an emer-' gency as just described owing to the valve or plug 12 being then closed, as above indicated.

-What, I claim as new is:

1. In a roofed oil tank having vent means and an outlet opening arranged in the upper portion thereof, crossed supports arranged in the upper portion of the tank and having their respective ends secured to the walls of the tank, a water receptacle of a contour similar to the contour of the tank having its walls snugly engaged with the inner surface of the walls of the tank and its bottom resting on the supports s0 that the upper edges of the walls of the receptacle lie flush with the upper edges of the walls of the tank, and means for securing the walls of the receptacle and tank together.

2. The combination with an oil tank having an open top and vent means and an outlet opening arranged in the upper portion: thereof, and a superimposed spaced roof, of supporting means arranged across the tank near the top thereof, a water receptacleof a contour similar to the contour of the tank In testimony whereof I afiix my signature in the presence of two Witnesses.
